Vantaa Sandåker revisited

Time sure flies... This was already the 11th excavation by yours truly on this awesome dwelling site from the neolithic stone-age. It was here in Vantaa Sandåker that I started my career in Community Archaeology while working at Heureka the Finnish Science Centre 1990-1997. The magnificient finds of detailed anthropomorphic and zoomorphic clay figurines from the excavations of the site has kept Vantaa Sandåker (Jokiniemi) in the limelight for decades.

One might argue that I have not got very far from where I started. This years excavation area was located only tens of meters from the areas we excavated between 1990-1994.

During the last day of excavations in 2024 we managed to find remains of a possible hearth in the uppermost area of the dwelling site, some 25 meters above sea level. After we had secured funding for a five-day community archaeology excavation from Vantaan Aikuisopisto it was time to take a clooser look at the hearth and its surroundings between 16.5-20.5.2025. The plan now is to conduct yearly community archaeology excavations of the site.

Some 15-20 people participated in this years excavation and the work progressed very well indeed. Already on day two it was possible to document the uppermost layer of the hearth. It proved to be almost round in shape and constructed of two layers of stones which were heavily firecracked . The soil inside hearth was sooty and contained many large fragments of charcoal. These will this week be sent to the Tandem Laboratory at Uppsala University for C14 dating.

The reason for the excavation in 2025 was this hearth that we stumbled upon during the last day of excavations in 2024.

The finds found in the area surrounding the hearth were extremely few due to the fact that the find layer had been almost completely "plowed away" when the area was used as a market garden. All the finds like pottery, flintartefacts and flint flakes however pointed towards the early and and especially the middle phases of the Typical Comb Ceramic Period (ca 5 800-5 500 BP).

During the last two days of the excavation we were able to make some trial excavation pits in order to plan next years fieldwork. Sadly most of the area proved to be equally demolished by ploughing and artificial levelling of the slope to build a house garden. However in area some 40 meters from this years excavation area a small piece of the site seemed to have been spared.

The finds from two of the pits in this area were especially promising. We will continue excavations here in May 2026. Register to the excavation here https://ilmonet.fi/course/V260058

Hiekkaharjuntie in Porvoo - First trial excavation excavations of the newly found stone-age dwelling site 10.5. – 14.5.2025.

This was a very exiting week. During a five day trial excavation we managed to find out a lot more about this well preserved Early Comb Ceramic period dwelling site that was discovered in 2021 by archaeologists Timo Sepänmaa and Johanna Roiha.

The excavation started out in sunny but rather chilly spring weather. The finds during the first two days only consisted of quartz flakes, burnt bone and a small slate chisel which seemed to point towards the site beeing from the Mesolithic rather than the Early Neolithic period.

Soon however we also started finding small fragments of pottery. The shape of the rimsherds and rather coarse ware pointed towards the pottery fragments beeing from the  Early Comb Ceramic period (ca 7 000 BP).

After five days of excavations it became evident that despite some damage had been caused when a gravel road was constructed in the northwestern part of the site most of the central part of the dwelling site were still intact. This part of it will excavaten in 2026 as part of the two-week-long NAU 2026 excavation.

Porkkala 1941-1956 project fieldwork May 5th-9th 2025

The 5th excavation season in Kirkkonummi Estby was a cold but succesfull one. Once again the team managed to pull of a remarkable feat excavating some 50 square meters of the 300 square meter Cold War period Soviet concrete and tile structure.

Part of the large concrete and tile structure excavated between 2021-2025.

This season the finds were mostly quite small in size and consisted of Soviet uniform buttons, tank crew uniform related artefacts, Soviet coins (1946-1954) and smoking related items.

The finds from the excavations of the site along with other items that have been collected in the area 1956-2025 will be shown in an exhibition in the nearby farmshop in 2026 commemorating the 70 year anniversary of the end of the Soviet prescence in Kirkkonummi 1944-1956.
